To run the Automation Engine Pilot on MAC, a Java Runtime Environment 1.6 is required. However, Apple does not allow Esko to distribute this version, so the installation of Java has to happen separately from the Automation Engine client.
The installation of Java should start automatically when the Java Runtime Environment is needed by the Automation Engine client installer. This automatic installation is currently provided by Apple and could change in the future.
On Windows, a Java Runtime Environment (JRE version 1.7) is distributed with the Pilot. The user does not need to install Java on the client machine.
